Carotid Body Tumor Resection

Carotid body tumor is a relatively rare chemoreceptor tumor. The normal carotid body is a small oval or irregularly shaped pink tissue with an average volume of about 6 x 4 x 2 mm, located in the outer sheath at the bifurcation of the common carotid artery. Surgical resection is generally required, and it is feasible to treat carotid body tumor resection. Treatment of diseases: cervical hemangioma neck cystic lymphangioma Indication 1. Carotid body tumor resection according to clinical signs and magnetic resonance (MRI) examination to understand the extent of the lesion. The tumor and the carotid artery were slightly coagulated, or the tumor and carotid artery were severely adhered, but the preoperative cerebral vascular Willis ring evaluation results were significantly decompensated. 2. The tumor and the carotid artery were removed together and the tumor and the carotid artery were severely adhered, and the cerebral vascular Willis ring was evaluated preoperatively. 3. Carotid artery reconstruction The tumor and the carotid artery are severely adhered, and the cerebral vascular Willis ring is not smooth enough. Contraindications 1, with systemic diseases, can not tolerate surgery. 2, local infection, not suitable for surgery. Preoperative preparation 1. CT, MRI or angiography should be routinely performed before surgery to determine the relationship between the tumor and the carotid artery. 2. Before the operation, there must be evaluation and examination data of the cerebrovascular condition, and the surgical plan and emergency plan should be completed. Surgical procedure 1. The incision tumor is located in the upper neck, and the oblique incision is made along the anterior border of the sternocleidomastoid muscle. If the tumor is located at a high position, protruding into the jaw or the pharyngeal side, an arcuate incision should be placed under the lower jaw. 2. The tumor is revealed to reveal the internal jugular vein and the common carotid artery. The internal jugular vein is pulled to the outside, and the carotid bifurcation and the tumor are separated upward along the common carotid artery. The carotid triangle is dissected and should be carefully separated on the surface of the tumor to fully reveal the relationship between the tumor and the carotid artery. The internal and external carotid arteries are freed above the tumor. 3. Remove the tumor after the fully free common carotid artery, internal carotid artery and external carotid artery are worn with rubber tube (be careful not to vagus nerve and sublingual nerve in the rubber tube and cause damage), from the lower neck of the tumor The adventitia of the artery is a deep plane, and the tumor is carefully peeled from the outside to the inside. The ventral exfoliation is often very difficult, easy to rupture, perforation and massive bleeding, and special care should be taken. If the vessel wall is perforated or ruptured during the stripping process, the rubber tube should be tightened immediately and the gap should be repaired with non-invasive needle suture. If there is a certain boundary between the tumor and the arterial wall, the tumor can be lifted up and separated upward along the artery wall, and the tumor is peeled off from the artery wall. 4. Wound treatment and suture flushing wounds, completely stop bleeding, set negative pressure drainage tube, suture wounds in layers, and dress up with sterile dressing. complication Neck pain.
